SHUTTER-WORKER.

, SPECIFICATION formingpart of Letters Patent No. 510,446, datedDecember 12, 1893.

Applicationfiled December 16, 1891- Serial No. 415,237. (No model.)

To all whom it may concern:

Be it known that I, ALBERT ROSENBERG, a citizen of the United States,residing at Baltimore,in the State of Maryland, have invented certainnew and usefullmprovements in Shutter-Workers, of which the following isa specification.

This invention has for its object to provide I a new and improvedshutter worker, and it consists in the features of construction and thecombinationor arrangement of parts hereinafter described and claimed,reference being made to the accompanying drawings, in which- Figure 1 isan under plan view of thenpper or movable leaf of a butt-hinge providedwith a toothed arc and forming part of my improved shutter-worker. Fig.2 is a side view of the same. Fig. 3 is an edge view and Fig. 4 a sideView of the lower or stationary leaf of the butt hinge. Fig. 5 is a faceview of the toothed wheel for engaging and operating the toothed are ofthe upper hinge-leaf. Fig. 6 is a view of the crank shaft with toothedwheel and locking pin. Fig. 7 is a view of a portion of the interior ofa window frame showing the position of the shutter-worker with theshutter locked open. Fig. 8 is an elevation of the locking device. Fig.9 is an end view of the shutter-Worker as seen from the outside of abuilding when the shutter is closed.

Referring to the drawings, the numeral 1 designates a portion of thewall of a building; 2 a portion of a window frame and 3 a part of ashutter or window blind.

The shutter-worker is connected with and operates the lower hinge of theshutter. The lower or stationary hinge-leaf 4., which is secured to theWindow frame as usual, is provided with the usual pintle 5 and with adepending arm 6 having its lower end curved outward away from and out ofline with said pintle. In the lower end of this arm 6 is a bearing 7 fora crank shaft 8 that is extended through the Window frame 2 and into theinterior of the building. On the inner end of this shaft 8 is a crank 9and on the outer end of said shaft is secured a toothed wheel 10 throughthe rotation of which the shutter is opened and closed. The upper ormovable hinge-leaf 11 is secured to the sh utter 3 in the usual mannerbut is preferably provided with a bracing arm 12 that is extended at aright angle to the main portion of the leaf in position to be secured tothe outside of the shutter stile. This arm 12 gives additional strengthto the hinge and at the same time serves to press the shutter flush upagainst the sill when the shutter is closed. The upper hinge-leaf 11 isprovided with the usual socket 13 for engaging the pintle 5 of the lowerleaf. On the lower part of the upper hinge-leaf is cast a toothed are 14with which the toothed wheel 10 is arranged to mesh. The toothed are 14is preferably strengthened by a bracket 15 intermediate said are and themain portion of the leaf and integral therewith.

As indicated by the lines X Z, Fig. 9, it will be seen that the centerof rotation of the toothed wheel 10 is out of line with the center ofrotation of the toothed are 14:, thus adjusting the leverage in such amanner as to greatly facilitate the operation of the shutterworkerwithout straining its several parts. This construction also permitsready removal of the shutter without unscrewing the hingeleaves, and,further, it provides such an arrangement of the toothed wheel 10 thatwhen the shutter is opened'all the way it does not strike against thebrick wall, but is prevented from so doing by resting against the saidtoothed wheel, thereby avoiding the tendency to break off the hinge.This is a very important and desirable feature in this type of shutterworkers.

The crank 9 on the inner end of the shaft 8 is provided with aperforation 16 that is countersunk or provided with a recess 17 in itsinher end to receive the laterally elongated head 18 of a pin 19 that isloosely supported in said perforation. To the inner side of the windowframe 2 is secured a locking plate 20 provided at suitable points withslots 21 into which the head 20 of the pin 19 can be pressed. After thewindow shutter has been opened or closed, or brought to any intermediateposition by means of the shutter-worker, the head of the locking pin 19can be pressed into one of the slots 21 and be partly turnedtherein toprevent its jarring or working out, and thus the shutter can be easilyand quickly locked in the desired position.

It will be observed that when the shutter is closed and locked on theinterior it cannot be pried up and lifted out of place, because whilethe shutter is in this position a portion of the toothed are 14 on theupper leaf of the hinge is below the lower leaf, and by reason of thestout depending arm 6 on said lower hinge leaf any attempt at strainingor bending the shaft of the wheel 10 will be prevented.

I am aware that it is common to operate window shutters from theinterior of a building by means of toothed gearing rotated by a crankshaft and, also, that looking devices have heretofore been provided forsuch m echanism; but this I do not broadly claim.

What I claim as my invention is l. The combination of the lowerstationary hinge leaf 4 having the pintle 5 and a depending arm 6provided with a journal hearing at its lower end, the upper movablehinge leaf 11 having the pintle socket 13 and provided on its lower edgewith a horizontally arranged toothedarc 14, a shaft 8 extended throughthe Window frame and through the bearingof the said depending arm on thelower hinge leaf, a toothed wheel 10 secured to the outer end of saidshaft in front of the said depending arm to strike the shutter whenopened, and means for operating the shaft and looking it in a fixedposition, substantially as described.

2. The com binanion of the lower stationary hinge leaf 4: having thepintle 5 and a depending arm 6 extended from below the piutle andhavingits lower end portion curved outwardly and provided with a journalbearing 7, the upper movable hinge leaf 11 having a pintle socket 13 andprovided on its lower edge with a horizontally arranged toothed are let,the shaft 8 extended through the window frame and through the journalhearing at the lower end of said depending arm, the toothed wheel 10secured to the outer end of said shaft in mesh with the toothed are sothat when the shutter is open it rests against said toothed wheel and isprevented from striking the wall of the building,the crank 9 foroperating the said shaft,and means for locking the crank, substantiallyas described.

In testimony whereof Iaffix my si gnat u rein presence of two Witnesses.
